Coast Range

The heavily vegetated, elongated Coast Range province has a varied geologic history. Its basement was formed by a volcanic island chain that collided with North America about 50 million years ago. The ancient volcanoes form many of the scenic headlands along the coast, and the sediments that have accumulated around them contain marine fossils that help unravel the area’s complicated geologic story.
